2006 Jeep Liberty

Engine Performance problem
2006 Jeep Liberty 6 cyl Four Wheel Drive Automatic 49,000 miles

When you frist start it up, it runs ruff, and keeps stalling. I have to keep my foot on the gas, and one on the brake to keep it moving. After running for awhile, till the engine temp comes up, then it runs fine all the way home. Start it the next day and the same thing all over again. Please HELP. Thanks Ted

Engine running rough or misfiring can be cause by the following: 1. Defective spark plug
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Idle air control valve.
